Objective To determine the long-term outcome of surgical repair of popliteal artery aneurysms (PAA). Methods A retrospective review of consecutive patients who underwent surgical PAA repair in two vascular surgery units between 1988 and 2006 was performed. Primary and secondary graft patency, limb salvage and patient survival rates were determined using Kaplan-Meier methods. Results 48 patients underwent repair of 63 PAAs (ligation and bypass = 45, interposition grafting = 18). The 5-year primary graft patency, secondary graft patency, limb salvage and patient survival rates were 75%, 95%, 98% and 81%, respectively. The 10-year primary graft patency rates were significantly lower for emergency cases (59%) compared with elective cases (66%) (p = 0.0023). Thirteen patients (16 PAAs) required a total of 20 late re-interventions. Duplex ultrasound was available in 33 of 45 PAAs treated by ligation and bypass. Five (15%) PAAs demonstrated perfusion of the aneurysm sac at median(range) follow up of 75 (1–246) months after primary repair and two of these required emergency re-operation. Conclusions These data demonstrate that surgical PAA repair is associated with excellent long-term durability and provide an important benchmark with which to compare results of endovascular PAA repair. Patients treated using the ligation and bypass technique should be enrolled in an aneurysm sac surveillance program.
